Electric Cars

In a fascinating convergence of automotive history and modern efficiency debates, a 1983 Ford Probe IV Concept, a vehicle designed over four decades ago, has emerged for sale, boasting a drag coefficient that outstrips many of today's cutting-edge electric vehicles. This unique prototype, a testament to early aerodynamic innovation, offers a rare glimpse into how car manufacturers once pushed the boundaries of design for optimal airflow. Despite its advanced design for its era, the particular model on offer is not a running vehicle but rather a significant artifact of engineering prowess, making it a distinctive acquisition for collectors and enthusiasts of automotive heritage.

Vintage Concept Car with Modern-Day Aerodynamic Prowess Hits the Market

In mid-March 2026, a remarkable piece of automotive history, the 1983 Ford Probe IV Concept (chassis #001), became available for purchase on Bring a Trailer. This concept car, a collaborative effort between Ford and the Italian design house Ghia, was conceived primarily for wind-tunnel testing, aiming to explore the extreme limits of low-drag vehicle design. With an astonishingly low drag coefficient of 0.152, it remarkably surpasses the aerodynamic efficiency of contemporary electric vehicles like the Lucid Air and Mercedes-Benz EQS, which feature coefficients of 0.197 and 0.20, respectively. The Probe IV Concept also pioneered features such as adjustable ride height. This specific prototype, however, is largely non-functional, lacking essential components such as an engine, transmission, brakes, and a steering system, although its front wheels can be manually adjusted. It exhibits several cosmetic and structural imperfections, including a sagging rear roof and missing mirrors. Previously part of a private collection belonging to the owner of Gullo Ford in Conroe, Texas, it was acquired by the current seller in 2024. Only two such prototypes exist, with the other, a more complete and functional version powered by a 1.6-liter turbocharged four-cylinder engine, currently housed at the Petersen Automotive Museum in Los Angeles. The auction for this historical vehicle is set to conclude on March 22, with bidding at $1,500 at the time of reporting.

This sale of the 1983 Ford Probe IV Concept serves as a compelling reminder that the pursuit of aerodynamic efficiency is not a recent phenomenon driven solely by the rise of electric vehicles. It highlights the visionary engineering efforts from decades past that continue to influence automotive design. While this particular model is not road-ready, its intrinsic value lies in its historical significance, offering a tangible connection to the evolution of car design and a pioneering spirit that sought to optimize performance through innovative forms. It prompts reflection on the trade-offs between pure design theory and practical manufacturing constraints, as modern production vehicles must balance aerodynamic ideals with rigorous safety standards and functional requirements. For collectors, it represents a rare opportunity to own a piece of engineering legacy that continues to resonate with contemporary automotive challenges.

Hennessey Performance has unleashed a powerhouse, the Chevy Silverado 1500 ZR2 "Goliath 700," addressing the power disparity between Chevrolet's robust off-road truck and its high-performing adversaries, the Ford F-150 Raptor R and Ram TRX. By integrating a supercharger, Hennessey has dramatically elevated the ZR2's output to a formidable 700 horsepower, making it a true contender in the elite segment of high-performance off-road vehicles. This exclusive offering is not just about raw power but also incorporates significant enhancements in aesthetics and suspension, catering to enthusiasts seeking an unparalleled driving experience both on and off the beaten path.

Chevrolet's Silverado 1500 ZR2 has always been recognized as a highly capable off-road machine, distinguished by its robust V-8 engine. However, its factory-tuned 420-hp 6.2-liter small-block engine falls considerably short when stacked against the 720 horsepower of the Ford F-150 Raptor R and the 777 horsepower of the Ram 1500 TRX. This noticeable power deficit left a niche for tuners like Hennessey to fill. Recognizing this gap, Hennessey Performance engineered the Goliath 700 to not only match but potentially surpass its rivals in sheer power and on-road presence.

The transformation into the Goliath 700 involves more than just a supercharger. Hennessey's comprehensive modifications include an intercooler system, a bespoke ECM tune, and a cat-back exhaust, all contributing to the remarkable 700 horsepower and 611 pound-feet of torque. These upgrades represent an astonishing increase of 280 horsepower and 151 pound-feet of torque over the standard ZR2. According to Hennessey, this powerhouse can accelerate from 0 to 60 mph in a blistering 4.2 seconds. While maintaining the ZR2's advanced Multimatic spool-valve dampers, the Goliath 700 also receives a BDS suspension setup, complete with new upper control arms, enhancing its off-road prowess and handling capabilities.

Beyond its mechanical upgrades, the Goliath 700 distinguishes itself with a more aggressive and imposing visual identity. Hennessey has adorned the Silverado with carbon fiber hood vents and a tailgate applique, adding a touch of high-performance luxury. New steel bumpers are installed not only to provide increased clearance for extreme off-roading but also to contribute to a more assertive aesthetic. The front bumper is further enhanced with integrated LED lights, a bull bar, and prominent Hennessey branding, symbolized by an "H" insignia. The truck rides on intricate 20-inch wheels wrapped in chunky 35-inch off-road tires, solidifying its dominant stance.

The interior of the Hennessey-modified Silverado ZR2 also reflects its exclusive nature. It features all-weather floor mats and headrests embellished with the Texas-based tuning company's embroidery, subtly reminding occupants of the vehicle's unique lineage. Each Goliath 700 is further marked by a numbered plaque on the center console, signifying its position within the limited production run of just 100 units. These exclusive trucks will be available through authorized Chevrolet dealers, and each comes with a limited warranty covering three years or 36,000 miles, providing peace of mind for its discerning owners.

The acquisition of a Hennessey Silverado Goliath 700 comes with a premium price tag of $139,950. This figure positions it significantly above the standard 2026 Silverado 1500 ZR2, which starts at $76,290. Furthermore, it outprices its direct competitors, the 2026 Ford F-150 Raptor R at $113,525 and the 2027 Ram 1500 SRT TRX at $102,590. This pricing reflects the extensive modifications, the exclusive nature of the limited production run, and the unparalleled performance enhancements that Hennessey brings to the already capable Silverado ZR2 platform.
